While connecting the battery, the ground was inverted with the VCC and vice versa. As a result, this capacitor burned out. I need to know the function of this part and if I can continue to work normally after what happened.
Hi,I want to make the system with stm32f4 series mcu. An important function of the system is to control the Ethernet speed.Is it possible to adjust the Ethernet speed with such detailed figures as 65Mbps, 38Mbps, and 300Kbps??If possible, how can I a...
Hi I want to use the STM32U5A9VJ6Q_SMPS inbuilt chip in one of my projects. I plan to run the chip with 3.3V. Is it feasible to run at 3.3V for all pin functions?
Is there any known way to detect if a double word 0xffffffff value has been programmed? I’m not seeing any quick way, other than finding out after getting flash error bits set. The bootloader I’m working with checks the sector for all 0xff to avoid e...
ADC1 clocked @ 65 MHz, pre-scaler of 8, 7 channels active, 640.5 cycles/conversion, 256 oversampling, interrupts, scan mode. The numbers suggest all channels will be converted 1x in (8/65000000) * 640.5 * 7 * 256 = 141 ms. But when I look at uwTick b...
Hi ,I am writing multiple chunk of each 48 bytes to Flash by following flash programming sequence mentioned in STM32 U5 Reference manual. However some chunks are written properly where some chunks are still remains 0xFF. Please let me know if anybody...
Hi, I am trying to implement PWM generation on PC06 from TIM8. The cubeMX is showing following warnings and not generating the clock on desired PIC_PC06??RGB LED is Adafruit NEO Pixel 7 https://www.adafruit.com/product/2226See the attached images and...
I am working on a project that uses a PWM on a timer to drive a buzzer. When the buzzer stops I need to set the output compare signal high. The timer set ARR to 250, and the compare value to 125, giving a 4kHz square wave with a 50% duty cycle. I...
I made several changes in ethernetif.c pbuf_ref(p); if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) { while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK) { } HAL_ETH_ReleaseTxPacket(&heth); } else { pbuf_free(p); } ////...
Dear All,I want to use trace on STM32h755So kindly let me know which trace/debugger has to use and what are the pins required.
